Based on what I observe around Boston, the use of precast concrete as a cladding system for highrise buildings is robust. I want to believe that modern precast will outlast the older systems. If I were a betting man I would assign modern panels a 75 year lifespan before cosmetic failure starts to evolve into comprehensive failure.
I'm also starting to rethink my attitude towards cavity walls as the be-all and end-all of enclosure systems. If panelized, barrier systems are the preferred method for large scale structures, then they must be okay. Right?
